Capacitor Materials

NKK’s major products are high quality separators, paper wound with aluminum foil inside. Separators for capacitors play an important role in isolating anode and cathode while maintaining the electrolyte. Separators are also characterized by their thickness of 15 to 130µm. Aluminum electrolytic capacitors are for instance used in energy saving and digital home appliances, the clean energy sector or for eco-cars.
